you should have named them horses' eyes. I love the light and details you captured, but dont you think the eye in the first one is looking a bit scary ? suggest you close up only on the eye for a change or get a slightly larger feature of the horse.
the eyebrows of the second and the hairs (?) of the third are brilliant. third is a bit overexposed, I believe, but very, very well taken. good job man, keep it up !
